Frequently Asked Questions about PolyGone

PolyGone stripping agents are unique formulations that remove polysulfide (PRC, ProSeal, Chem Seal) and silicone RTV sealants from metal, ceramic, glass, composite, and some plastic substrates. PolyGone is effective at removing silicone RTV and polysulfide (polysulfide) sealants at room temperature. They are fast acting and environmentally Friendly as opposed to regular used solvents. PolyGone 310-AG is approved for use on endorsed by NavAir and AFRL and approved on Bombardier’s 100/200, 700 & 900 Series aircraft. PolyGone 505 is also excellent at silicone removal from Roll-Royce RB211 engines.

PolyGone is primarily used to remove cured polysulfide (PRC, Flamemaster, AC Tech) and silicone (GE, Dow, Rhodia, NuSil, Wacker). PolyGone can also remove some other tenacious sealants and adhesives. PolyGone can used in aviation, marine, window and any industrial application where polysulfide is used.

PolyGone penetrates the polymer to cleave it into smaller parts emulsifying the polymer. This emulsification prevents re deposition and enables easy rinsing. PolyGone reacts chemically with the sealants, therefore temperature is very important. We recommend a minimum temperature of 70°F and around 80°F for good performance. In industrial situations, you can heat to 110°F for enhanced performance.

PolyGone has passed Boeing’s D6-17487 with the exception of paint softening and Douglas’ CSD #1 with the exception of acrylic crazing. Even with scraping, paint will still get damaged so we do not view the paint softening as a limitation. Keep in mind that this relates to top-coats, not primer. PolyGone will not remove fuel tank primers. As for the crazing, as long as you are using the product on a stretched acrylic window, like what are found on pressurized aircraft, you will not have any issues.

We do not recommend use on windows from non-pressurized aircraft or helicopters. PolyGone has also been tested by NavAir and AFRL for use on Navy and Air Force aircraft along with Bell Helicopters. It you attend the Bell Helicopter training class, they recommend PolyGone 310-AG for use on the transmission housing to avoid damage to the magnesium.

PolyGone will also quickly react with latex, vinyl and numerous types of paints & coatings. PolyGone 305 and 310-AG are safe on composites and stretched acrylic (pressurized cabins) not regular acrylics (non-pressurized aircraft). The PolyGone 505 will react with composites.

The reaction of PolyGone with the sealant starts in under 1 minute however, it will take several minutes before you will see anything. Complete removal depends on the type of polymer, thickness of the polymer, temperature, agitation, and age of the polymer.

PolyGone will remove 100% of all the polysulfide (PG-305 & PG 310-AG) and/or silicone (PG-505) it comes in contact with; however, the exact amount depends on the type and age of the sealant. For many applications, a 6-oz. container of the gel will remove around 4-6 linear feet of 1/4” bead. As there are hundreds if not thousands of sealants on the market your exact amount will vary.

Yes and no. PolyGone does not dissolve polysulfide like sugar dissolves in water. The PolyGone chemically breaks the bonds of the polysulfide into small parts so that it can emulsify. This is why we also refer to it as a digester.

Yes. PolyGone is compatible with numerous metals and plastics. Ultrasonics actually decreases the amount of cleaning time by 75%. Heat, up to 49°C (120°F), can also be used to decrease cleaning time by 50%.

Yes, elevating the temperature of the PolyGone will improve its performance. See above. On the low side, we recommend a temperature of at least 65°F in the application area. Any lower temperature and the product performance is very slow.

Since this is a chemical reaction, all reactions stop. The PolyGone is spent when the item/part no longer gets clean in the typical cleaning time for your particular application. When you first start using PolyGone, it is worthwhile to note the initial cleaning time for reference and comparison.

PolyGone may be disposed of with your other solvents. The material does have a high heating value and can be burned for fuel value. Consult with your environmental department for final ruling as regulations vary by county and state.

The PolyGone can continue to be used until it no longer digests the sealant. Once the material no longer works it must be disposed. However, do not add additional material to your bath. Run each bath until the material is spent. This is the most economical method of use.
